The ratchet 75 is fixed to the front upper part of the sector 80, and has a plurality of teeth 76 arranged so as to draw an arc centered on the support pin 85. The teeth 76 of the ratchet 75 are formed so that the claws formed at one end of the pole 70 mesh with each other as the pole 70 swings. In the parking brake operation device 1, the pawl 70 is engaged with the teeth 76 of the ratchet 75, so that the parking brake lever 10 is restricted from rotating around the support pin 85 in the release direction. When the release knob 60 is pushed, the release rod 50 slides backward, and the pole 70 swings as the pole connecting portion 57 moves, so that the meshing of the ratchet 75 with the tooth portion 76 is released. Therefore, in this case, the parking brake lever 10 is allowed to turn in the releasing direction, and the parking brake can be released via the brake cable.

(Activation and release of parking brake)
The operation of each part when operating the parking brake or releasing the operation of the parking brake using the parking brake operating device 1 configured as described above will be described.

First, the case where the parking brake is operated and the braking force is applied to the vehicle will be described. In this case, the driver rotates the parking brake lever 10 in the operating direction in the parking brake operation device 1. Specifically, the driver holds the grip member 40 of the parking brake lever 10 and pulls it upward. As a result, the parking brake lever 10 rotates upward (that is, clockwise in FIG. 1) about the support pin 85.

As the parking brake lever 10 rotates in the operating direction, the brake cable connected to the base end portion 12 of the parking brake lever 10 is pulled, so that the parking brake connected to the other end of the brake cable operates. A braking force is applied to the vehicle.

Then, as the parking brake lever 10 rotates in the operating direction, the pole 70 swings around the pin 71 against the biasing force of the spring 65 and sequentially gets over the teeth 76 of the ratchet 75. Thereafter, when the rotation of the parking brake lever 10 in the operation direction is stopped, the pawl 70 maintains the meshing with the tooth portion 76 of the ratchet 75 and restricts the rotation of the parking brake lever 10 in the release direction. To do. By restricting the rotation of the parking brake lever 10, the state of the brake cable is also maintained, and the operation state of the parking brake is maintained.

Next, the case where the parking brake that is operating is released and the braking force acting on the vehicle is removed will be described. In this case, the driver performs the pushing operation of the release knob 60 while once turning the parking brake lever 10 in the operating direction, and the release knob 60 is pushed into the parking brake lever 10 in the release direction (in FIG. Rotate clockwise.

When the release knob 60 is pushed while rotating the parking brake lever 10 in the operating direction, the release rod 50 slides backward to the parking brake lever 10 against the urging force of the spring 65. . As a result, the pole 70 swings around the pin 71, and the meshing between the pawl of the pole 70 and the tooth portion 76 of the ratchet 75 is released. By entering this state, the parking brake lever 10 can be rotated in the release direction.

As the parking brake lever 10 is turned in the release direction, the brake cable connected to the base end portion 12 of the parking brake lever 10 is loosened, so that the operation of the parking brake connected to the other end of the brake cable is activated. The braking force for the vehicle is removed.

(Configuration of release rod 50)
Next, the configuration of the release rod 50 according to the present embodiment will be described in detail with reference to the drawings. As shown in FIGS. 2 and 5, the release rod 50 is formed by pressing a metal plate material, and includes a mounting projection 51, a spring accommodating portion 52, a long hole 56, and a pole connecting portion 57. have.

The mounting protrusion 51 is formed so as to protrude in the right direction of the release rod 50 by pressing the metal plate material and bending the front end portion of the release rod 50. That is, the mounting protrusion 51 protrudes in the right direction orthogonal to the rotation direction (vertical direction) of the parking brake lever 10 and the sliding direction (front-rear direction) of the release rod 50. As shown in FIGS. 7 to 9, the mounting protrusion 51 is fitted into the mounting hole 61 of the release knob 60 to hold the release knob 60 at the front end of the release rod 50.

The spring accommodating portion 52 is formed in the rear portion of the mounting projection 51 by penetrating the inside of the release rod 50 in the left-right direction (that is, the vehicle width direction of the vehicle). The spring accommodating portion 52 has a protruding piece 53, a protruding shape portion 54, and a front end edge portion 55, and accommodates a spring 65 therein.

As shown in FIG. 8 and the like, since the spring 65 is housed in the spring housing portion 52 formed in the release rod 50, the spring 65 is compared with the case where the release rod 50 is inserted and disposed. It becomes a small diameter and can be miniaturized. Here, the component cost of the spring 65 is strongly influenced by the amount of the metal wire constituting the compression coil spring, and can be reduced by downsizing. That is, according to the parking brake operation device 1, it is possible to reduce the product cost of the parking brake operation device 1 by reducing the component cost related to the spring 65.

As shown in FIGS. 5, 6, etc., the protruding piece 53 is formed to protrude along the axial direction of the release rod 50 from the front end edge 55 of the spring accommodating portion 52 to the rear. The projecting piece 53 is located at a central portion in the opening dimension of the spring accommodating portion 52 in the vertical direction, and is inserted into the spring 65 when the spring 65 is disposed inside the spring accommodating portion 52. Since the spring 65 is arranged at a predetermined position inside the spring accommodating portion 52 by being inserted by the protruding piece 53, according to the parking brake operating device 1, the spring 65 is moved in the direction along the axis of the release rod 50. The urging force of 65 can be applied to the release rod 50, and thus the urging force of the spring 65 can be appropriately applied to the pole 70.

Further, with respect to the axial direction (that is, the front-rear direction) of the release rod 50, the projecting piece 53 is formed to project from the front end edge portion 55 located in front of the opening edge of the spring accommodating portion 52 with a projecting piece dimension D. ing. The protruding piece dimension D indicates half or less (for example, about 1/3) of the accommodating part opening dimension W which is the opening dimension of the spring accommodating part 52 in the axial direction of the release rod 50.

Here, the length of the protruding piece 53 in the axial direction of the release rod 50 affects the positioning function of the spring 65 in the spring accommodating portion 52 and the workability of attaching the spring 65 to the spring accommodating portion 52. More specifically, if the length of the protruding piece 53 is long, it will be inserted deeply into the spring 65, so that the positioning function of the spring 65 in the spring accommodating portion 52 is improved. Since the space occupied by the protruding piece 53 is increased, the workability of attaching the spring 65 to the spring accommodating portion 52 is lowered. On the other hand, if the length of the protruding piece 53 is short, the protruding portion 53 is shallowly inserted into the spring 65, so that the positioning function of the spring 65 in the spring accommodating portion 52 is deteriorated. Therefore, the workability of attaching the spring 65 to the spring accommodating portion 52 is improved.

That is, according to the parking brake operating device 1, as shown in FIG. 6, by setting the protruding piece dimension D of the protruding piece 53 to be equal to or less than half of the housing opening dimension W (for example, about 1/3), The length of the protruding piece 53 inserted into the spring 65 and the space around the protruding piece 53 inside the spring accommodating portion 52 can be sufficiently secured, and thus the positioning function of the spring 65 in the spring accommodating portion 52 is ensured. And the workability of attaching the spring 65 to the spring accommodating portion 52 can be made compatible.

As shown in FIGS. 5 and 6, the protruding portion 54 is formed at the lower end edge extending in the front-rear direction of the opening edge of the spring accommodating portion 52, and the inner side direction (ie, upward) of the spring accommodating portion 52. Protrudes toward. And when the spring 65 is arrange | positioned inside the spring accommodating part 52, the protrusion-shaped part 54 always contacts with respect to the lower end of the spring 65 (refer FIG. 8). According to the parking brake operating device 1, vibration of the spring 65 inside the lever main body 15 can be suppressed by contact with the projecting shape portion 54, and thus chatter noise caused by vibration of the spring 65 can be suppressed.

The front end edge portion 55 is formed above and below the protruding piece 53 in the opening edge located on the front side of the spring accommodating portion 52. Each front end edge portion 55 is formed so as to draw an arc that protrudes toward the front side, and is arranged symmetrically about the center of the protruding piece 53. As shown in FIG. 8 and the like, when the spring 65 is arranged between the holding piece 24 and the front end edge 55 inside the spring accommodating part 52, the urging force of the spring 65 also acts on each front end edge 55. To do. As described above, each of the front edge portions 55 is arranged in line symmetry with the protruding piece 53 as an axis and draws an arc, so that the spring 65 is spring 65 by the urging force of the spring 65 itself. And the center of the protruding piece 53 are moved to a position where they coincide. That is, according to the parking brake operating device 1, the spring 65 can be easily disposed at an appropriate position in the spring accommodating portion 52 of the release rod 50, so that the urging force of the spring 65 can be applied to the release rod 50. Can be made to act properly.

Further, an elongated hole 56 is formed in the rear portion of the release rod 50 from the spring accommodating portion 52. The long hole 56 is formed so that its long diameter is along the front-rear direction of the release rod 50, and is inserted through a pin 58 for caulking and joining the first half 20 and the second half 30. The release rod 50 can slide in the front-rear direction along the axial direction of the operation unit 11 by the cooperation of the long hole 56 and the pin 58.

A pole connecting portion 57 is formed at the rear end of the release rod 50 and is connected to the pole 70. Thereby, in the parking brake lever 10, the displacement by the sliding movement of the release rod 50 acts on the pole 70, and the attitude | position of the pole 70 can be changed.

As shown in FIGS. 2 and 5, the release rod 50 can be made of a metal plate material. Specifically, the release rod 50 forms various configurations such as the mounting protrusion 51 and the spring accommodating portion 52 by a simple processing step of pressing (for example, bending or punching) the metal plate material. Is possible. Therefore, according to the parking brake operating device 1, the release rod 50 having the spring accommodating portion 52 and the like can be manufactured with a simple processing step.

(Configuration of release knob 60)
The configuration of the release knob 60 according to the present embodiment will be described in detail with reference to the drawings. As shown in FIG. 1, FIG. 2, etc., the release knob 60 is attached to the front end portion of the release rod 50, and is formed of synthetic resin so as to have an attachment hole 61 and a hollow portion 62. .

In the release knob 60 according to the present embodiment, the front side is formed in a substantially cylindrical shape, and the semi-cylinder is formed in the rear right side part. As shown in FIGS. 7 and 8, the mounting hole 61 is formed to penetrate to the right in a semi-cylindrical portion located on the rear right side of the release knob 60, and the mounting protrusion 51 of the release rod 50 described above. Are fitted. On the other hand, a hollow portion 62 is formed in the front portion of the release knob 60 having a cylindrical shape. The hollow portion 62 is a gap portion formed in a semi-cylindrical shape on the left front side of the release knob 60, and suppresses the occurrence of sink marks and voids when the release knob 60 is molded with synthetic resin.

As described above, in the release knob 60, the right direction, which is the depth direction of the mounting hole 61, is orthogonal to the rotation direction (vertical direction) of the parking brake lever 10 and the sliding direction (front-back direction) of the release rod 50. Yes. Therefore, even if the slide movement (front-rear direction) to the release rod 50 and the release knob 60 is performed, the mounting protrusion 51 does not move in the direction of coming out of the mounting hole 61, and the release knob 60 is removed from the release rod 50. Can be prevented.

(Parking brake lever assembly process)
Then, an example of the assembly process of the parking brake lever 10 which concerns on this embodiment is demonstrated. In the following description, components such as the release rod 50, the release knob 60, and the spring 65 are arranged between the first half 20 and the second half 30 and assembled.

Specifically, the operator arranges the spring 65 inside the spring accommodating portion 52 from above the first half 20 and the release rod 50 arranged on the work table in a state where the spring 65 is compressed in the axial direction. At this time, the spring 65 is disposed between the front end edge 55 of the spring accommodating portion 52 and the holding piece 24 and is inserted through the protruding piece 53. Accordingly, when the spring 65 is restored from the compressed state to the original state, the spring 65 is positioned between the front end edge 55 and the holding piece 24 in the spring accommodating portion 52 and applies a biasing force to the release rod 50. (See FIG. 8).

Thus, with the release rod 50 and the release knob 60 arranged on the first half 20, the second half 30 is stacked from above. Thereby, according to the parking brake operating device 1, components such as the release rod 50 can be arranged inside the first half 20 and the second half 30.

At this time, the second half 30 is laminated with the inner wall faced downward with respect to the release rod 50 and the like disposed on the first half 20 and penetrates the spring accommodating portion 52. The tip of the holding piece 24 of the first half 20 enters the insertion hole 34 of the second half 30. That is, as shown in FIG. 9, the holding piece 24 is disposed across the entire vehicle width direction between the first half 20 and the second half 30, so that the end portion of the spring 65 is the vehicle width. Even when it is displaced in the direction, the urging force of the spring 65 can be received.

Although omitted in the above description, before the second half 30 is stacked on the first half 20, the pole 70, the sector 80 provided with the ratchet 75, and the like are arranged. The arrangement of these members may be before the second half 30 is laminated, may be before the release rod 50, the release knob 60, and the spring 65, or the release rod 50, the release knob 60, and the spring 65. It may be after the arrangement.

Projecting from the front edge. Thereby, the parking brake operating device 1 can achieve both the positioning function of the spring 65 in the spring accommodating portion 52 and the workability of attaching the spring 65 to the spring accommodating portion 52.

In the half cylindrical portion 31 of the second half 30, an insertion hole 34 is formed facing the formation position of the holding piece 24 in the first half 20. Accordingly, when the first half 20 and the second half 30 are joined to each other, the tip of the holding piece 24 is inserted into the insertion hole 34. As shown in FIG. 9, the proximal end of the holding piece 24 is formed integrally with the first half 20, and the tip of the holding piece 24 is inserted through the insertion hole 34 of the second half 30. Therefore, the parking brake operating device 1 can receive the urging force of the spring 65 acting on the holding piece 24 not only in the first half 20 but also in the second half 30. Further, since the holding piece 24 is arranged in the vehicle width direction inside the cylindrical operation portion 11, the end of the spring 65 is displaced in the vehicle width direction, and the spring 65 is prevented from sliding down. Can do.
